Specification of Letters Patent.

Application filed May 2, 1910. Serial No. 558,769.

T 0 all whom it may concern:

Be it known that I, li Ian'rm OHRYNO- wnncrr, a citizen of the UnitedStates, and

a resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Dasher forIce-Cream Freezers, of which the following is a full, clear, and eX- actdescription.

The invention is an improvement 1n ice cream dasher-s, and has in Viewsuch a device which will enforce the rapid traveling of the cream fromthe center of the can upwardly and outwardly to the sides, and alsoforce the cream upwardly and inwardly at the sides as it is scraped fromthis wall of the can, whereby the freezing of the cream takes placerapidly and uniformly throughout, and in this way preventing the creamfrom freezing and eaking at the bottom of the can before that at thecenter and top solidifies.

The invention further has in View a dasher which will thoroughly mix thecream and render it palatably smooth, as by pre' venting the formationof crystals of any substantial size.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of an ice cream dasher embodying myinvention, the dasher being shown within the can, with the latter invertical section; Fig. 2 is a perspective View of one of the scraperblades of the dasher; and Fig. 3 is a section through the central shaft.

In the construction of the dasher I make use of the customary centralvertical dasher shaft 5, which is pointed or otherwise shaped at thebottom to fit in the socket of the can, and square or of other angularform at the top to connect it to the operating mechanism, as is thecommon practice. Adjacent to the upper and lower end portions of theshaft, cross-bars 6 extend therethrough and are radially arranged withrespect to the shaft, with one cross-bar positioned at approximatelyright-angles to the other. These cross-bars serve to carry scraper orcircumferential blades 7 for the dasher, each blade having a spiral bendadapting it to force the cream upwardly from the bottom of the can asthe cream is scraped from the sides. The scraper blades are shown to beconstructed of substantial width, and each provided throughout itslength with a number of perforations 9, which serve to effect a thoroughmixing of the cream and break up the crystals when the dasher is inoperation.

A vertical conveyer 10, centrally arranged on the dasher, forces thecream from the bottom of the freezer upwardly and outwardly toward thesides, and is carried by the dasher shaft 5, the conveyer preferablycomprising a series of V-shaped spiral blades 11, with the inner portionor base of each blade adjoining or continuous with the inner portions orbases of the blades above and be low, with the points of the bladesspaced some distance apart, whereby the cream as it is lifted by theconveyer has an opportunity to flow outwardly between the blades to thesides of the freezer can.

lVith the dasher thus constructed, the

'cream is kept constantly traveling at the center from the bottom of thecan upwardly and outwardly, and as it freezes to the sides of the can,is driven toward the top and center to the conveyer 10 and in this wayprevents the cream from caking at the bottom and sides of the freezerbefore the center and top of the cream has solidified.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In an ice cream dasher, a central vertical dasher shaft havingcross-bars at the top and bottom respectively, radially arranged and ata substantial angle to each other, spiral scraper blades attached to theouter ends of the cross-bars, discharging upwardly, and anupwardly-discharging conveyer at the center of the dasher and carried bythe dasher shaft.

2. In an ice cream dasher, a central vertical dasher shaft, and anupwardly-discharging conveyer carried by the shaft, having approximatelyV-shaped conveyer blades spirally arranged on the shaft, with the innerportion or base of each blade adjoining the inner portions or bases ofthe adjacent blades.

8. In an ice cream dasher, a central vertical dasher shaft, andrelatively wide, fiat, spiral, circumferential blades carried by theshaft and discharging upwardly, the blades spaced from the shaft andmaking a turn of approximately 90 in the length of the dasher, with theflat faces of the blades arranged substantially normal to the directionof movement.

4. In an ice cream dasher, a central dasher conveyer arranged todischarge upwardly when revolved in one direction, and circumferentialspiral dasher blades fixed relatively to the central conveyor andinclined to dis- 10 charge upwardly and inwardly to the cen- E twosubscribing witnesses.
